Parker's Series 7132 Liquid Petroleum Gas LPG Hose Factory Assemblies provide excellent service across a wide variety of industrial and commercial LPG/propane delivery and supply applications. The industrial rubber hose resists stiffening and cracking and stays flexible to -40°F for ease of handling, and is available in long continuous lengths for remote delivery/transfer applications. Series 7132 hose assemblies provide robust service in challenging applications.

• UL21
• DOT
Safety/Technical:
• Design Factor: 5:1
Warnings:
• Couplings attached with bands or clamps may reduce the working pressure of the hose assembly to less than the maximum rated working pressure of the hose. Refer to NAHAD Industrial Hose Assembly Guidelines.
• LPG:
-Series 7132 hose assemblies installed on on-road vehicles must meet Department of Transportation (DOT) requirements. Factory assemblies (3/4" and larger) are pressure tested, one of the fittings is etched with a unique DOT certification number, and a document incorporating the identical certification number accompanies each shipment. Metal DOT identification bands are also attached at an additional charge per customer request.
Anhydrous Ammonia:
-Do not use Series 7132 with anhydrous ammonia.
• CNG:
-Do not use Series 7132 for CNG engine applications in on-road vehicles, or for high pressure CNG dispenser/transfer applications (typically 2900 psi or greater). In other applications—where CNG is regulated to pressures within the rating of Series 7132—apply the guidelines for natural gas applications stated above. Always review and adhere to all applicable government and industry regulations and standards prior to installing this hose in a CNG or natural gas application.
• Natural Gas:
-Do not use hose for natural gas service where fixed/rigid pipe is more appropriate due to reduced permeation and overall strength and durability. Use rigid pipe, non-permeable tubing or hose with barrier constructions to convey natural gas whenever possible.
-The molecules of natural gas are small, enhancing their ability to permeate through standard rubber hose constructions. The permeation process is more rapid as the working pressure increases, and natural gas accumulates with potentially dangerous consequences. Series 7132 may be used for natural gas service, but ONLY under ALL of the following conditions:
-The application must be in a well-ventilated environment: Outdoors, or indoors with significant continuous air movement.•It is an industry recognized occurrence that LPG will permeate through the hose wall during operation and storage, therefore Parker LPG hoses are produced with a pinpricked cover from the factory to relief the expansion of liquid propane to gaseous propane as it permeates through the hose wall. Great care must be taken when discharging LPG hose to reduce the incident of damaging the hose from explosive decompression. RELEASE LPG AT A RATE THAT ALLOWS THE TRAPPED LPG TO DISSIPATE AS SLOWLY AS POSSIBLE. See the Tech Alert – LPG Hose Evacuation Process for more information from your LPG Distributor.
